1 '0 all whom it may concern:

Be it known that I, JOSEPH N. SzAno, a

citizen of the United States, residing at" Throop, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Wall-Mold, .ofwhich the follow-- ing is a specification.

This invention relates to an improved apparatus'for constructing concrete buildings, one of its objects being to provide means whereby theminimum'waste of material results from the construction of the .forms so that the cost of construction is greatly reduced.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that change-s in the precise embodiment of the invention herein disclosed, can be made within the scope'of what is'claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawingsz-Figure 1 is a plan view of a portion of a foundation or basement wall in process of construction, the parts of the form or mold being shown in place. Fig. 2 is an end elevation of the wall and the forms used in the construction thereof. Fig. 3 is a perspective view of a portion of the inner form.

In constructing the basement wall of a building, a plurality of boxes 1 are used to constitute the inner form. These boxes canbe of any desired proportions and are adapted to be placed one above the other and end to end so as to present an inner form of the desired shape and proportions. The boxes can be held together at their ends by driving stakes 2 into the ground and securing the stakes to the boxes by the use of nails or the like. Top strips 3 can be fastened upon the boxes and at any desired intervals braces 4 can be extended downwardly and inwardly from the boxes and to the ground, as shown clearly in Figs. 1 and 2. The boxes constituting the inner form of each wall may be held together by a tie wire 5 extending lon gitudinally around them, this tie wire being connected to a turn buckle 6 so that it thus becomes possible to bind the wire tightly around the boxes and thus clamp the boxes securely together. As shown in Fig. 1, the boxes can be disposed at angles to each other so as to produce a wall of any desiredcontour. After the boxes have been set up to complete the inner form of 'the wall, the outer form can be erected. This outer form is made 'up solely of timbers7 to be used subsequently as rafters, studding, posts or the like, in the building under construction. These timbers are placed one-upon the other until a stack ofthe desired height is pro-. duced, the timbers being held together at their ends by end stakes 8'nailed or otherwise. fastened to them. A,

"VVherever it is desired to form a groove in the outer surface of the basement wall, one course of timbers is extended inwardly beyond the inner faces of the other timbers and where it is desired to produce a bead upon the basement wall, the timbers consti tuting one course are set outwardly from the inner surface of the form. After-the timbers forming the outer form have been assembled so as to produce a surface or th'e'desired contour, they can be held to the inner form by means of cross strips 9 bolted or otherwise secured to both forms and, as shown in Fig. 1, certain of the top strips 3 can be extended over and fastened to the top timbers 7. Furthermore, stakes 10 or the like can be driven into the ground so as to contact with the outer surface'of the outer form and these stakes can be nailed or otherwise fastened to the timbers and also to the adj acent top strips 3. Additional stakes can also be located wherever desired, as for example, at the free ends of the timbers, as shown at 11.

After the forms have been set up in the manner described, the space between them can be filled with concrete in the usual manner, it being understood that any interstices between the boxes 1 forming the inner form can be filled in any desired manner, as by means of wooden inserts 12 or the like.

After the basement wall has set, the inner and outer forms can be taken apart and. as before stated, the timbers constituting the outer form can be subsequently used in various parts of the structure as in the construction of the floors, partitions, roof, etc. The boxes making up the inner form can of course be used over again in the construction of other buildings. By utilizing forms such as herein described the waste of material which has heretofore rendered the construc- (inn ("fvflmgl'et-( h h k mluvml t0 the mininnun.
